for posting image from web url you will do following steps :

STEP 1: get bitmap from URL :

see this post

for getting image bitmap from URL

STEP 2 :

Store Bitmap in Images.Media temporarily and after send it you can delete it

String path = Images.Media.insertImage(getContentResolver(), 
                            bitmapiamge, "title", null);
Uri screenshotUri = Uri.parse(path);

Intent sharingIntent = new Intent(Intent.ACTION_SEND);
emailIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
sharingIntent.putExtra(Intent.EXTRA_STREAM, screenshotUri);
emailIntent.setType("image/png");

startActivity(Intent.createChooser(emailIntent, "Send email using"));

and for sending bitmap to facebook wall see this post :

Code to set the background image to the relative layout from one activity to another

in the first activity see the code shown below

protected void onActivityResult(int requestCode, int resultCode, Intent data) 
 {
    // TODO Auto-generated method stub
    if(requestCode == 1011)
    {
        if(resultCode == RESULT_OK)
        {
            image.setImageURI(data.getData());
            imageUri = data.getData();

            String filePath[] = {MediaStore.Images.Media.DATA}; //A column name which to be return
            Cursor c = getContentResolver().query(imageUri, filePath, null, null, null);
            c.moveToFirst();
            int index = c.getColumnIndex(filePath[0]);
            String path = c.getString(index);//actual path of file in sa card
            c.close();

            if(path!=null)
            {
                //Bitmap bmp =BitmapFactory.decodeFile(path);
                SharedPreferences.Editor editor = pref.edit();              
                editor.putString("image",path);//set the path of file into the SharedResources
                editor.commit();
            }
        }

    }   
}

code to set background image

 void setLayoutBackground()
{
    SharedPreferences pref = getSharedPreferences("style_pref", 0);
    String path = pref.getString("image",null);
    Bitmap myBitmap = BitmapFactory.decodeFile(path);
        BitmapDrawable d = new BitmapDrawable(getResources(),myBitmap);
        layout.setBackgroundDrawable(d);
}
